Pixel pitch, also known as dot pitch, is the distance between adjacent LEDs in an LED display and is, therefore, synonymous with pixel density or LED clusters. The dot pitch of certain large-screen CRTs is 0.51 mm, whereas that of typical computer screens is between 0.25 and 0.28 mm. The resolution of a screen is directly proportional to the dot pitch.ĭot pitch may be seen on both cathode ray tube and liquid crystal display screens. Resolution is often expressed in millimeters (mm), with lower values indicating better resolution, or as a rate, such as dots per inch “dpi” (with a larger number meaning higher resolution). It is also known as line pitch, stripe pitch, or phosphor pitch. What is Dot Pitch?ĭot pitch is a specification for a computer screen, printer, image scanner, or other pixel-based devices that defines the spacing between the dots used to show an image. This metric is used by software to display a document on the screen at its “real size.” The pixel density of a digital image may be found by dividing the total number of pixels by the size of the display in square inches.
The PPI of a display depends on its physical dimensions (inches) and the total number of pixels (in the horizontal and vertical directions, respectively). PPI measures how much detail can be displayed on a square inch. The PPI measurement is often used to describe the screen resolution of a display.
The greater the PPI, the sharper the picture. It is the number of pixels in a digital picture per square inch, and it is also the maximum number of pixels a screen can show at once. Pixels per inch (PPI) is a measure of resolution in a digital image or video display.
